Fascin-1 expression is associated with EMT and recurrence in thymic carcinoma: a clinicopathologic study.

Fascin-1, an actin-bundling protein, plays a crucial role in cancer cell motility, invasion, and epithelial-mesenchymal transition (EMT). While its significance has been demonstrated in several malignancies, its clinical relevance in thymic carcinoma remains unclear. We retrospectively analyzed 10 surgically resected thymic carcinoma cases treated at Kochi University Hospital from 2008 to 2024.

Unraveling the impact of crizotinib to promote megakaryopoiesis for alleviating thrombocytopenia in myelodysplastic neoplasms.

Current therapeutic options for myelodysplastic neoplasms (MDS)-associated thrombocytopenia are limited. Megakaryocyte maturation might be an innovative therapeutic strategy because its dysregulation profoundly contributes to MDS pathogenesis. Here, we identified crizotinib, a clinically approved anti-cancer drug for anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer, as a potent inducer of megakaryocyte maturation.

Empagliflozin reduces liver fibrosis by restoring catechol-O-methyltransferase activity associated with magnesium levels.

Catechol-O-methyltransferase (COMT), a magnesium (Mg)-dependent enzyme, metabolises catecholamines. Diabetic patients exhibit hypomagnesemia and sympathetic overactivity compared with non-diabetics. Sodium-glucose cotransporter 2 (SGLT2) inhibitors increase serum Mg levels in diabetic patients.

Clinical and microbiological effects of a propolis toothpaste in patients with periodontitis under supportive periodontal therapy: a randomized double-blind clinical trial.

Objectives: Propolis possesses antibacterial, anti-inflammatory, and antioxidant properties. While its application in oral care has garnered significant attention, evidence supporting its effectiveness against periodontal bacteria is limited. This study used a randomized double-blind protocol to assess the safety and efficacy of toothpaste containing propolis compared to a placebo in patients undergoing supportive periodontal therapy (SPT).

Pilot study of a novel resection extent determination method using bone single-photon emission CT-standardized uptake value in medication-related osteonecrosis of the jaw.

Objective: Surgery is the standard treatment for medication-related osteonecrosis of the jaw (MRONJ). However, there are few reports on the appropriate extent of the bone resection. This pilot study explores the feasibility of a new method for estimating the extent of resection using bone single-photon emission CT (SPECT)-standardized uptake value (SUV).

The PKM2 activator TEPP-46 suppresses cellular senescence in hydrogen peroxide-induced proximal tubular cells and kidney fibrosis in CD-1 mice.

Aim/introduction: Senescence is a key driver of age-related kidney dysfunction, including diabetic kidney disease. Oxidative stress activates cellular senescence, induces abnormal glycolysis, and is associated with pyruvate kinase muscle isoform 2 (PKM2) dysfunction; however, the mechanisms linking PK activation to cellular senescence have not been elucidated. We hypothesized that PKM2 activation by TEPP-46 could suppress oxidative stress-induced renal tubular cell injury and cellular senescence.

Effect of introducing somatic mitochondria into an early embryo on zygotic gene activation†.

Unlike differentiated somatic cells, which possess elongated mitochondria, undifferentiated cells, such as those of preimplantation embryos, possess round, immature mitochondria. Mitochondrial morphology changes dynamically during cell differentiation in a process called mitochondrial maturation. The significance of the alignment between cell differentiation and mitochondrial maturity in preimplantation development remains unclear.

Compound #41 Targets Acute Myelogenous Leukemia by Inhibiting the Wnt/β-catenin Signaling Pathway.

Background/aim: Aberrant activation of the Wnt/β-catenin signaling pathway contributes to the pathogenesis of acute myelogenous leukemia (AML). Thus, targeting this pathway offers a promising therapeutic strategy against AML. Here, we synthesized a novel dipeptide-type inhibitor of the Wnt/β-catenin signaling pathway, compound #41, and explored its anti-tumor effects on AML cells.

An 11-mer Synthetic Peptide Suppressing Aggregation of Aβ25-35 and Resolving Its Aggregated Form Improves Test Performance in an Aβ25-35-Induced Alzheimer's Mouse Model.

There is a high demand for the development of drugs against Alzheimer's disease (AD), which is related to the misfolding and aggregation of Amyloid-β (Aβ), due to the increasing number of patients with AD. In our present study, we aimed to assess the aggregation inhibitory effect of various synthetic YS-peptides on Aβ25-35 to identify an applicable peptide for clinical use for AD treatment and prevention. Suppression and aggregate resolution activities of YS-peptides against Aβ25-35 were evaluated using a Thioflavin T assay and scanning electron microscopy (SEM).

IL36G-producing neutrophil-like monocytes promote cachexia in cancer.

Most patients with advanced cancer develop cachexia, a multifactorial syndrome characterized by progressive skeletal muscle wasting. Despite its catastrophic impact on survival, the critical mediators responsible for cancer cachexia development remain poorly defined. Here, we show that a distinct subset of neutrophil-like monocytes, which we term cachexia-inducible monocytes (CiMs), emerges in the advanced cancer milieu and promotes skeletal muscle loss.

In utero morphological and functional properties of bovine trophoblastic vesicles.

In many mammals, including ruminants, pregnancy requires pregnancy recognition signaling molecules secreted by the conceptus; however, the mechanism underlying pregnancy establishment in cattle remains unknown. Trophoblastic vesicles (TVs) are artificially produced from the extraembryonic tissues of the elongating conceptus and may be useful tools for understanding conception. This study investigated the morphological and functional properties of TVs in comparison to those of intact conceptuses.

HMGA2 promotes platelet-neutrophil complex formation and pulmonary tissue damage in myelodysplastic syndromes.

High mobility group AT-hook 2 (HMGA2) is an architectural transcription factor that functions as an oncogene in various cancers. Although overexpression of HMGA2 has been reported in several myeloid malignancies, its role varies considerably in different disease contexts. Here, we identified a distinct role of HMGA2 as a mediator of noninfectious pneumonia in myelodysplastic syndrome (MDS).

[Pathogenesis of myelodysplastic syndromes by excessive mitochondrial fragmentation].

Myelodysplastic syndromes (MDS) are a group of heterogenous hematopoietic stem cell (HSC) malignancies characterized by ineffective hematopoiesis in which clonal progenitor expansion occurs alongside impaired myelopoiesis. Inflammatory signaling activation due to dysregulated innate immunity is also a hallmark of MDS pathogenesis. We recently established a useful preclinical tool that recapitulates bona fide MDS phenotypes and gene expression profiles based on previously unreported co-mutations discovered during our clinical surveillance of mutations in patients with MDS.

Feature extraction of particle morphologies of pharmaceutical excipients from scanning electron microscope images using convolutional neural networks.

Scanning electron microscopy (SEM) images are the most widely used tool for evaluating particle morphology; however, quantitative evaluation using SEM images is time-consuming and often neglected. In this study, we aimed to extract features related to particle morphology of pharmaceutical excipients from SEM images using a convolutional neural network (CNN). SEM images of 67 excipients were acquired and used as models.

TGA and NMR relaxation measurement of nonmesoporous silica to investigate the amount of hydrolysis product in acetylsalicylic acid adsorbed on silica.

This study investigated a crucial surface property of silica that contributes to the chemical stability of acetylsalicylic acid (ASA) physically adsorbed on silica. Hydrophilic nonmesoporous types of silica were selected, and the number of hydroxyl groups on silica (N) was evaluated using thermogravimetric analysis (TGA). The ASA-containing silica was stored at 40 °C in drying conditions, and the amount of ASA degradation was quantified based on salicylic acid.
